  • Publication number: 20190089553
    Abstract: The present invention is directed to a CATV & MoCA® device, such as a passive, point of entry (POE) splitter or a RF amplifier. In the passive, POE splitter, a resistive splitter network connects plural “MoCA® only” ports, e.g., four, five or eight, to two or more “MoCA® and CATV” ports. The MoCA® only ports and MoCA® and CATV ports are connected to a MoCA® rejection filter, which is in turn connected to an input connected to a service provider. In the passive, POE splitter or the RF amplifier, an intuitive female coaxial port layout and marking scheme assists technicians with correctly connecting the POE splitter or RF amplifier to the correct coaxial cables at a customer's premises. The port layout also simplifies the circuitry design parameters on a printed circuit board (PCB) by orienting the “CATV & MoCA®” output ports at similar distances from a CATV input port of the POE splitter or RF amplifier.
